PFCs may be more toxic to the immune system than current dioxin exposures

Boston, MA—A new study finds that perfluorinated compounds (PFCs), widely used in manufactured products such as non-stick cookware, waterproof clothing, and fast-food packaging, were associated with lowered immune response to vaccinations in children. It is the first study to document how PFCs, which can be transferred to children prenatally (via the mother) and postnatally from exposure in the environment, can adversely affect vaccine response.

The study appears in the January 25, 2012 issue of the Journal of the American Medical Association (JAMA).

“Routine childhood immunizations are a mainstay of modern disease prevention. The negative impact on childhood vaccinations from PFCs should be viewed as a potential threat to public health,” said study lead author Philippe Grandjean, adjunct professor of environmental health at Harvard School of Public Health.

PFCs have thousands of industrial and manufacturing uses. Most Americans have the chemical compounds in their bodies. Prior studies have shown that PFC concentrations in mice similar to those found in people suppressed immune response, but the adverse effects on people had been poorly documented.

The researchers analyzed data on children recruited at birth at National Hospital in Torshavn, Faroe Islands during 1999-2001. A total of 587 participated in follow-up examinations. Children were tested for immune response to tetanus and diphtheria vaccinations at ages 5 and 7 years. PFCs were measured in maternal pregnancy serum and in the serum of children at age 5 to determine prenatal and postnatal exposure.

The results showed that PFC exposure was associated with lower antibody responses to immunizations and an increased risk of antibody levels in children lower than those needed to provide long-term protection. (Antibody concentrations in serum are a good indicator of overall immune functions in children.) A two-fold greater concentration of three major PFCs was associated with a 49% lower level of serum antibodies in children at age 7 years.

“We were surprised by the steep negative associations, which suggest that PFCs may be more toxic to the immune system than current dioxin exposures,” said Grandjean.

The PFC concentrations are similar to or slightly below those reported in U.S. women, and most serum PFC levels in Faroese children at age 5 were lower than those measured in U.S. children aged 3 to 5 years in 2001-2002.

Evidence for the causes of environmental diseases have been around for a long time

The doctor and scientist Doris Rapp is one of those who not only practice environmental medicine, but has also made environmental medicine the most important thing in her life. The American spent two weeks in Germany. The reunion with Prof. Rapp was very productive and we were lucky enough to spend a beautiful day on the Moselle. Here is a small summary.

Researcher documented environmental disease

I met Prof. Rapp for the first time at a congress in Bad Emstal about 18 years ago. It was a crucial experience. In her presentation, she showed a video about a teacher who became ill from contaminated carpeting in the school. The teacher was filmed during a reaction to contaminated dust from the carpet. This video vividly conveys to the viewer what MCS is and what a reaction can look like. At that time I was at the very beginning of my own illness and had had similar reactions to certain pesticides. The teacher experienced convulsions and fell unconscious. I thought “my goodness, that’s me, that’s exactly like me, that’s what you have…“ After the lecture I spoke with Prof. Rapp and that was the beginning of an ongoing exchange of information and an interesting friendship. We met again at conferences in Germany, Holland and in the U.S., visited each other in Germany and the United States and exchanged e-mails. When I visited her in Scottsdale, she showed me one of her video archives. She had stored thousands of videos of children whom she had treated. They showed the patients during and after therapy and during testing of foods, mold, pollen, dust mites or chemicals. They displayed impressive evidence that can remove any last doubts as to the existence of environmental illnesses and allergies.

We can no longer ignore environmental illnesses

Dr. Binz and his wife invited the environmental doctor for this most recent visit to Germany. We had actually arranged to meet for a trip along the Moselle, which would start before lunch. We had a warm reunion and before we knew it we had already exchanged information and ideas and were in the midst of planning for future projects.

“I’m over 80 years old now and have no children, I don’t really need to be doing all this and I could be enjoying my peace at this age, but I see what’s going on, and I simply cannot remain silent. We have so many chemicals in our environment, in the food we eat, in the water we drink and the air that we are constantly breathing. They affect each of our body systems and we can no longer ignore this. Almost every second person in my country has cancer and that is just not acceptable”, says Doris Rapp.

“The politicians and the public must realize the impact the flood of chemicals has on us and no one should keep insisting that we do not know where all the increasing diseases that occur are coming from. The evidence is there. We have animal testing to prove it. That’s why, as a doctor, I ask: How much more has to happen before we admit to the real causes? I won’t accept hearing when one says, “Yes, but there’s nothing we can do about it.” Yes, there is, because you can educate yourself and there’s a hell of a lot you can do,” says Prof Rapp, who is enraged about the current situation.

Solutions are often very simple

Prof. Rapp is no one who can be at odds with the world and ignore the solutions. She is in the process of writing another book. “It will be a small book, only 30 pages. Every reader can easily understand how he/she can shape his environment in order to stay healthy. The tips in this book will not cost anyone a fortune, they can easily be implemented without major expense. It will help anyone who wants to change something and wants to improve his health. The doctor cites two examples:

“Many people react to foods, but are not sure towards which foods. Expensive tests are not necessary. I advise people to think about what they eat most, foods that they downright crave. Experience has shown that these are the foods that are eaten every day and most likely those which cause reactions. The solution: omit the suspected food for a week. You can test one food after another. This costs nothing! ”

“Some people live in a house that is contaminated with pollutants or contaminated by mold. My experience is that five out of seven people can improve their health by 70% if they obtain a high quality air cleaner that is capable of filtering hundreds of chemicals from the air in your home. Such a device may cost a bit, but I have often seen patients who got better over night. So it’s worth it if you are unable to directly move out of the apartment or house.”

The new book will be published this year, and Professor Rapp has authorized me to translate it into German. She also gave me permission to translate videos and other books into our language, contributing knowledge to allergy sufferers and chemically sensitive people in the German-speaking countries, helping them to find a way back into life.

A trip along the Moselle

During the drive to the historic Moselle wine village, Bernkastel, to Traben-Trabach and the drive back to Trier, Prof. Rapp was bursting with innovative ideas that we will begin to put into action in the next few months and they will benefit the environmentally ill in many ways.

Let me live!

Patrick is 19. His American football gear is in his closet, and in the corner of his room his electric guitar lays on the shelf next to the brilliant lyrics he wrote. His songs have a meaning, not just modified, banal versions of some well-worn songs that were eventually on the top of the charts. No way. Patrick’s music gets down to business and strongly suggests that the songwriter is not a wimp, but instead confident and that he has something significant to say. When Patrick wrote the songs/music, he went to high school, which earlier posed no problem for him, and he enjoyed a life outside of school as well. His buddies were always with him. Life then was to be lived! But now the American football equipment, the guitar, the unfinished recordings, and song books remain on the dusty shelves.

Those were the times

When Patrick lies on his bed in his room it seems like decades since he was with his band buddies on the stage. Sometimes he has flashbacks where he again sees the faces of the girls in front row of the stage, glowing, looking reverently up and so moved by the band’s damn good music. When these flashbacks return, Patrick is reminiscent of the life he used to live. Patrick would like to scream really loud so everyone can hear:

“My body and my pain hold me prisoner. I cannot leave and live like others. A broken body makes me a cripple. It forces me to not always do things that I would like to do. But I want to live.”

Causes and effects

Patrick is sick from chemicals and his body has developed an extreme form of chemical sensitivity (MCS). Some chemicals have the capacity to sensitize the body. In medicine, this is well known that some chemicals like formaldehyde, isocyanates, and some pesticides are able to cause illness. Everything has played a role in Patrick’s current condition. His father was a chemist and had 30 years of contact with chemicals which are capable of damaging genes. No one can define precisely the effects of the countless years of exposures from the not so harmless chemical cocktails where Patrick’s father worked. The fact is, that Patrick’s father, because of work-related health issues, no longer has his health and is seriously ill. Perhaps the house where the family lived also played a role in the illness. Seven times they had high water which left mold on the walls. The walls were washed extensively with chlorine, a highly toxic chemical. Also the wood preservatives in the house could have played a part in Patrick’s state of health.

Others have lived at least

The average age of people who are chemically sensitive, is from 35-45 years, according to studies. There are also sufferers who are much older and some who are still toddlers, but the majority of sufferers had a life before MCS. For Patrick, it’s different:

“Excuse me, I don’t want to offend the others, but the other MCS sufferers were allowed to enjoy prior life experiences (youth, school, training, travel, friends, partnership, etc.), but I was denied everything from the beginning. The best time of life, my youth, has not been granted to me. On the contrary, I am going through hell, but no one is interested, because they do not believe me.”

Ciao buddy

After Patrick broke down completely, the compassion of his buddies and classmates was just great. They came to visit him and provided him with information from school. That gave him the opportunity to continue his school for awhile. When that was no longer possible, he tried getting his education on the internet, via a correspondence school. But now that is over. No more calls, no more visits. Patrick experiences unbearable pain as he feels like he too is covered in dust like his guitar. The girlfriend he had whom he wanted to build a life with, now also lives a life without him, perhaps with someone else. Patrick experiences pain on another level besides just the excruciating physical pain of the illness. He is furious and says:

“I cannot believe that since I’m not out there, I must not be forgotten and do not exist. My struggle must not be in vain.”

“It is hard to accept that everything I have achieved to this point is destroyed.”

“I have resigned myself that I will probably always remain living alone. There is no compassion for this disease. In fact, on the contrary, I am immediately excluded. What girl or young woman is prepared to make such a sacrifice, and how will I even find a person when I need to live a life of isolation? Forget it. This also applies to other friendships as well. ”

“Although various people helped me earlier, now only two friends remain – I’ve always given everything and now … I’m just dropped, since I cannot keep up and have become too annoying or too complicated to all the others.”

To go out at least once

Besides all the bad luck Patrick and his parents experienced in the past, they also lost their most faithful companion too. So Patrick’s mother bought a new dog so that her son has some life in the house and finds some comfort through the love of an animal. The decision was good for the dog and he is very fond of Patrick:

“As much as I would love to be in nature for a couple of hours with our dog for training or just playing only with him, I am not even granted this.”

Simply cut the strings and let the frustration out

If Patrick was frustrated, it was hard to miss. He grabbed his guitar and the sparks were flying as he sang until the walls shook. That has not happened often, but when it did, everyone in the house knew after two minutes. Music is life and a way to express yourself, to let out what the mind has suppressed. But even allowing the frustration and the anger to be let out, is no longer possible for Patrick:

“Playing guitar and singing means so much to me, but my damn body does not even allow that. The muscle weakness and pain again slow me down, and of course, my dream of American football is over.”

MCS means in the worst stage of a “life” in total isolation

Patrick is one of the MCS patients who having a life outside the four walls is impossible. It should not be confused that these people do not want to be, among others, but on the contrary, the wish and desire to do something with other people remains every day around the clock. It is not a psychological problem or fear of people. The body simply gives up when exposed to chemicals. Car exhaust, heater exhaust gases, perfumed people, houses, from which wafts the cleaning products. All chemical cocktails present a difficulty for chemically sensitive people to have a chance to move about.

A short contact with the outside world means having extreme pain, seizures, difficulty breathing, collapse, or unconsciousness. The same applies for visiting. If someone comes to visit, the joy for Patrick can quickly lead to disaster. The deodorants or residues from the dry cleaners in the jacket, fabric softeners, which cannot be totally washed out will make the visit impossible. Utter nonsense? Not at all. Who will make the effort to find appropriate ingredients for “everyday products” that will bring about severe consequences for a man whose body is hypersensitive? What companies will makes the effort to accommodate hypersensitive individuals as they produce products? Not even most doctors will attempt to understand this chemical hypersensitivity. This is due partly out of ignorance, because they have never heard of the disease, and simply because they lack time to investigate further. And if doctors are not smart and declare the disease as a quirk of convenience, how can ordinary people understand those with MCS?

Patrick’s opinion on MCS:

“MCS is the worst disease out there; sometimes I wish I was a paraplegic. I know this sounds harsh, but I would not be so isolated, left alone, not credible, and would have no pain. I could travel in spite of this handicap, going almost everywhere, going to concerts, meeting friends, and possibly make training, and, and. “

The whole family is ruined

Patrick’s parents are willing to do anything for their son, so he can have his life back. But MCS is too complex to just fight the disease with medicine and a few natural remedies. One must start by establishing a clean living environment. Patrick and his father would need a living space that is chemical-and mold-free as much as possible. But how do you implement that? The house in which they have is hard to change due to the financial loss due to his father’s illness.

Help from authorities? No

Patrick should actually have a good case for the authorities to help, but because he has no education, there is no funding, no basic security, which is humiliating for the young man. His mother says:

“We get help from nowhere, in fact, it is quite the opposite. We are harassed by authorities and they make demands on Patrick which he cannot satisfy. Anyone who can count to three must see that. But nobody takes the trouble to look at the misery, instead, decisions are made that are devoid of any humanity. Yes, Patrick virtually exists only on the card. This illness ruined my two men and those who might know how to help and change things for us, look away too easily! ”

“Many people ask me, how has this total isolation been for over the last two years? They say to me, “I would go mad …. I would go crazy … I imagine the bad, and, and …” They also ask, “Where does Patrick, or where do you get the strength to keep going?”

The response from Patrick’s mother: “You can see that Patrick lives and we also manage. Somehow we are probably fighting spirits and do what we try to be bold, brave, and strong willed to survive. The struggle for justice makes us stronger. “That’s what Patrick’s mother says to the outside world, but inside she often thinks, how long does will the body last, like the heart muscle. Every day she must be available around the clock for her men. Every day is actually a struggle for survival, for Patrick, as well as his father.

Optional: a human decision

That which was given to Patrick and his parents since March 2009, is staggering. His parents submitted an application to determine his level of disability. Now a court ruling says that the 19-year-old man who is suffering from unbearable pain all day, and reactions to chemicals must go into a hospital. The hospital has assured the court that it is equipped for emergencies so there shouldn’t be any problems.

• What if he’s there and collapses completely? Who bears the responsibility for him then?
• Who pays to stay in a hospital environment abroad, because in Germany there is no help?
• Can a normal emergency procedure help him to bounce back?
• What if not?

There are no environmentally controlled hospitals for MCS patients in Germany. No hospitals can assure a complete freedom from chemical exposures at all. The hospital rooms discussed in a previous CSN article which are in Hamburg for the environmentally ill, are still not in full operation and they are also only for medical intervention, not for environmental treatment. Thus Patrick’s health would possibly be further compromised by this current court ruling the way it now stands.

So far, instead of support costs caused

Administrative expenses have already cost a fortune for Patrick, a 19 year old, with unbroken will to live. Legally, there is the possibility of seriously ill people remaining in their homes, and being examined within the safety of their own four walls. For Patrick, allowing this would be an act of humanity. This young man wants nothing more than for his disability to be determined. His disability and disease are detected nowhere better than in his own home where everyone can see with their own eyes what the illness actually means for Patrick and his family.

More attention needed to the disease factor in indoor pollutants

The awareness of the importance of uncontaminated food and pollution-free products in everyday life is growing worldwide. People are striving for a healthy and unpolluted living environment. Especially noteworthy are efforts that have been observed recently in Norway. In this Scandinavian country, efforts are prioritized to protect children, particularly against pollutants and allergens. One of the most active pioneers is Kjell Aas, a retired professor who supports the Norwegian Asthma and Allergy Association, with his profound knowledge. This scientist is anxious to clear ignorance about environmental and pollution-related diseases. He clarifies the facts to the authorities and population in ways which are understandable.

Environmental diseases are not mysteries, but scientifically explainable

For many people it is still difficult to understand that polluted air can also cause health problems or symptoms beyond just the respiratory tract. Research has delivered to us today only fragmentary explanations, but there are some entirely understandable explanations and solid scientific evidence of things not delivered to us, which Kjell Aas tries to make as general knowledge for the public.

The scientist Kjell Aas said, “Medical science has not yet managed to explore all the biochemical mechanisms behind the disease. The same goes for the so-called environmental diseases, such as hyperactivity, migraines, and multiple chemical sensitivity (MCS). To think that these environmental illnesses are something mysterious or inexplicable, or even that they are psychologically conditioned is just incorrect. This can be explained by one or more biochemical reactions. Both the physical and mental functions and activities are regulated by more or less complex chemical processes. The reactions are dependent on the dose and individual tolerance levels.”

Individual biochemistry sets the pace

“From a scientific aspect,” says Kjell Aas, “one must internalize that our internal biochemistry relies on the smooth functioning of a variety of cells with specific receptors and signal systems operating, and upon thousands of enzymes and co-enzymes. These biochemical processes can lead inhibitory and stimulatory mechanisms and integrated “amplifier systems” to gain significant effects.”

Kjell Aas says that the following is important for the public to realize, “Every person is an individual with his/her own individual biochemistry. A few milligrams of cocaine can change the personality and emotional life of an individual,” says the scientist, and continues, “or imagine alcohol having the same affect on the population, but as everyone knows, the tolerance threshold is different for each unique individual.”

The air we breathe daily

The scientist points out in his illustrative design, that adults consume 12 to 15 kg of air per day, and those gaseous chemicals are in the air we breathe, in a more or less high concentrations. Some of these gases combine with others, making them more harmful. These include ozone and other gases that lead to oxidation processes.

In addition, we take in particles in the air we breathe each day without ceasing. We breathe millions of fine particulate matter every hour of every day. These include chemical substances that are associated with the particulate matter which are in a position to pass as easily as breathing gases, and to move fully into blood, lymph and tissue fluid, the researcher points out.

Children are not little adults

Kjell Aas thinks special attention should focus on improving the current situation for children. He justifies this by saying that children can tolerate very little and will get sick easily from chemicals. “We have a variety of cells in our body,” the scientist explained, “all based on chemicals. The chemicals must agree to allow the cells to function properly and then the body will not get sick. ”

The Norwegian elaborated his statement and says, “If an unwanted chemical substances are inhaled, then the chemical balance is upset and so are the cells, and thus we get sick. The cells are blocked by these unwanted chemicals and cannot send out important chemical messengers responsible for our health.”

“Who exactly needs to understand these statements?” Kjell Aas wonders. It is important for all of us to realize the significant consequences for children, in particular, whose bodies are still under construction and development. This enlightenment is exactly what Kjell Aas hopes to awaken in all of us in hopes that we all begin to act accordingly. The Norwegians therefore ask in conclusion that we should internalize the following important fact:

“The air in a room which is acceptable for children, it is also acceptable for adults, but indoor air which is not acceptable for adults, can already make children ill.”

When you have MCS and you are exposed to certain toxic chemical agents, a series of symptoms are initiated automatically like irritation of the respiratory tract, tachycardia, headaches, mental confusion, dizziness, nausea, extreme fatigue or pain. These symptoms don’t get better until you cease contact with the chemical agent that produced it. The symptoms can last days or even weeks.

What is Multiple Chemical Sensitivity?

Multiple Chemical Sensitivity (MCS) is an acquired chronic illness, not a psychological one, which manifests itself with multisystemic symptoms as a reaction to a very small exposure to chemical products, normal everyday chemicals but unnecessary ones, like perfumes, air fresheners or laundry softeners.

The symptoms, which are chronic and they become acute in a crisis, include fatigue and respiratory, digestive, cardiovascular, dermatological and neurological problems.

MCS is a syndrome with four grades of severity, so not all of us who are sick suffer the same level of disability and isolation.

It is important to note that MCS is not an allergy.

It is an illness which has been known since the 1950s, but it has yet to be recognized by the World Health Organization (WHO), despite that there are more than 100 research articles that support the organic basis of MCS, that the number of people affected is increasing rapidly, at a younger age, and that the European Parliament includes MCS in the growing number of illnesses related to environmental factors. MCS has already recognized as a physical disease in Germany, Austria and Japan.

What percentage of the population has MCS?

There are no studies in Spain, but it is thought to be affected between 0.5% and 12% of the general population, according to the grade.

In countries where there are statistics about this illness, we see that the amount of people that have MCS is not small. According to the Environmental Health Association of Quebec, 2.4% of Canadians have MCS. According to Professor Martin L. Pall, PhD, the prevalence of severe MCS in the U.S is approximately 3.5% of the population.

So MCS is not a “rare disease,” which are the ones that affect less than 0.05% of the population. MCS is an emerging and hidden disease.

Chemical products are toxic and they affect us all. Chemical products are linked to illness like cancer, asthma, allergies, autoimmune diseases or any other illness of environmental origin.

How can you know that you are developing MCS?

The most common symptom is to notice unbearable chemicals which one did not notice before. One stops tolerating various chemical agents like cleaning products, perfumes, tobacco smoke, car emissions, air fresheners, etc.

You also may stop tolerating alcohol, dairy products or gluten. You also may develop intolerance to various foods and medications.

Often there are other environmental intolerances: to heat, to cold, to noise, to vibrations, to sunlight and to electromagnetic fields (computers, high power lines, telephones, cellular phone antennas, microwaves, etc).

MCS entails the loss of tolerance of chemical products in susceptible persons and there are two ways of developing MCS: from one single exposure to toxics at a high dose (fumigation, for example) or by many exposures to small amounts over the years. In the second group there are an increasing number of people with CFS/ME and FMS who, with the years, also develop MCS.

How is MCS diagnosed?

The diagnosis is clinical, based on the symptoms. There are no tests to diagnose MCS and other medical conditions must first be ruled out.

For the diagnosis, doctors use the questionnaire QEESI (Quick Environmental Exposure and Sensitivity Inventory) which is a sensitive and fast questionnaire instrument with five scales used to evaluate a person’s level of chemical sensitivity or intolerance.

6 consensus criteria for the definition of MCS:

1. A chronic condition.
2. Symptoms recur reproducibly.
3. Symptoms recur in response to low levels of chemical exposure.
4. Symptoms occur when exposed to multiple unrelated chemicals.
5. Symptoms improve or resolve when trigger chemicals are removed.
6. Multiple organ systems are affected.

When you have MCS and you are exposed to certain toxic chemical agents, a series of symptoms are initiated automatically like choking, irritation of the respiratory tract, tachycardia, headaches, mental confusion, dizziness, nausea, diarrhea, extreme fatigue and/or pain. These symptoms don’t get better until you stop being in contact with the chemical agent that produced it. The symptoms can last days or even weeks.

How is MCS treated?

Because of the pathophysiological bases of this syndrome are still unknown, there is no specific treatment for MCS. But there are a lot of treatments that help to control MCS and improve our health (sauna, supplements, homeopathy, etc.), and it’s very important to find a specialized doctor who studies our case, because each patient is different, depending on the genetic, the associated pathologies and the MCS grade.

Besides the treatment, is very important to put into practice the Environmental Control. Environmental Control is to basically avoid, as much as possible, any exposure to toxics or chemical substances. But in spite of this, MCS is chronic and persistent and it can reduce the quality of life of the sufferers.

Environmental Control is to avoid the chemicals or foods that may trigger reactions, avoid humid environments and avoid environments that could cause irritation (smoke, gas). This requires that we substitute all beauty and cleaning products with ecological ones without aroma; eat organic and non-processed foods (eliminate those we don’t tolerate) cooked using non-toxic cookware; filter the drinking water and also the water for cooking and showering; use a carbon-filter mask in situations in which there are a high concentration of toxics; get an air purifier; use ecological clothing with organic fabrics and organic dyes; avoid or minimize exposure to electromagnetic fields and in general remove everything that that we don’t tolerate (furniture, clothing, cosmetics, etc.). Sometimes is even necessary to change our residence. The Environmental Control benefits the MCS sufferer and also his entire family and it’s recommended for people with allergies or asthma in other countries. It’s also recommended for people with Chronic Fatigue Syndrome and Fibromyalgia.

Environmental Control: basic guidelines and tips (in Spanish).

Scientific evidence

In September 2008, was published the study “Is multiple chemical sensitivity a learned response? A critical evaluation of provocation studies” by Goudsmit and Howes at Journal of Nutritional & Environmental Medicine, which concluded that MCS is related to chemicals and it’s not a psychological illness.

In May 2009, Professor Anne C. Steinemann and Amy L. Davis of the University of Washington published a compilation of research on MCS with more than 100 peer-reviewed journal articles that support a physiological basis for MCS.

After that compilation, 2 important studies have been published:

In October 2009, the Journal of the Neurological Sciences published the study “Brain dysfunction in multiple chemical sensitivity” done by the Department Of Pulmonology of the Hospital Vall Hebron of Barcelona (Spain).

And at the end of April 2010 has been published the study “Biological definition of multiple chemical sensitivity from redox state and cytokine profiling and not from polymorphisms of xenobiotic-metabolizing enzymes” done by the IDI Institute of Rome (Italy) at the Toxicology and Applied Pharmacology – Elsevier.

Also last year, General and Applied Toxicology, 3rd Edition, published a chapter on MCS done by Researcher Martin Pall, PhD entitled “Multiple Chemical Sensitivity: Toxicological Questions and Mechanisms.”

Today there are 100,000 different chemicals constantly circulating in the environment, and the impact of the vast majority of these chemicals on the human organism is not known.

According to physician Stephen Hawking, Earth is at risk of a devastating disaster, and life can only be carried on by colonizing outer space.

What concerns him most is a potential asteroid collision with Earth which would wipe out life. However, I do not think we need to wait for this disaster. Man already carries out the mission of wiping out life on Earth pretty well!

Life has existed on Earth, our planet, for more than 3½ billion years. Homo sapiens appeared about 50,000 years BC, and until about 100-150 years ago, mankind communed well with nature and had until then, a lifestyle that only intervened to a limited extent in nature’s sensitive ecosystems.

However, a drastic change occurred approximately 150 years ago. Industrialization started and manufacturing and refinement processes could be enhanced by using steam, gas, oil, and electricity as power sources.

In the 1950s, the consumption of chemicals exploded – it became trendy to produce food additives, chemicals, detergents to ease housewives daily chores, and personal care products full of chemicals, etc.

Uncritical Manufacturing and Consumption of Chemicals

The result of this development is that today over 100,000 different chemicals are constantly circulating in the environment, and we do not yet know the impact of the vast majority of these chemicals on the human organism. Yet, today the cocktail effect of chemicals is being gradually discussed. A number of various chemicals together are much more harmful than single isolated chemicals. However, the motivation to investigate into this problem is not particularly high. A number of chemicals have a hormone-like-effect thus resulting in presexual maturity, childlessness, etc. It is a known fact that some chemicals are cancer-producing, but even this fact is being ignored to a large extent.

Pesticides Are Sprayed by Greedy Farmers

Farmers spray increasingly more aggressively with a huge number of various pesticides – substances designed to kill living organisms: pests, weeds, and fungi. It is a known fact that these pesticides certainly seep down into the groundwater. But what is being done about it? Oh yes, limit values are set forth on how much pollution is allowed in our drinking water. Limit values are set for how much toxic waste our food may contain. That is indeed sheer madness. Without protest, we accept eating, drinking and breathing in toxic waste. If pesticides are designed to kill living organisms, what makes us believe that these harmful chemicals are harmless to humans?

Chemical Disasters Have Become Everyday Occurrences

Nearly every day we are being flooded with stories on TV and in newspapers about various chemical disasters. A tidal wave of poisonous mud buries entire villages in Hungary. Contaminated plots of land are detected and chemicals are dumped around in the open countryside. The industry sends huge quantities of toxic wastewater and toxic smoke out into the environment, thus causing harmful damage to humans and animals. Certain fish are no longer edible due to heavy metals contamination. Even polar bears, living so far away from civilization, are exposed to chemicals and pollution via their food, thus developing deformed genital organs. The air is thick with pollution, and we incinerate fossil fuels in increasing quantities. We have gradually developed ”immunity” to all these gruesome stories. The madness goes on, driven by man’s tendency toward greediness.

Environmental Diseases such as MCS Are Results of All This Chemical Production and Pollution

Over the last 50 years or so, gradually, increasing numbers of people turn up, developing environmental diseases such as MCS. No wonder that the weakest of us is defeated by this devastating chemical pressure, foreign to the human body, as well as by the increasing spread of wireless devices, also being a devastating and unnatural strain on the human organism.

Man was created to live commune with nature, so even if it feels ”natural” to live as society does today, having daily contact with and consumption of hundreds of chemicals, the body is of course, not geared to defend against all those substances foreign on the human body. Some members of society become ill from this overwhelming chemical build up of pressure and develop chemical sensitivity.

Why Do Politicians, Scientists, Physicians, and Others Deny the Existence of the Environmental Disease MCS?

• If animals become ill from chemical filth, why shouldn’t a number of people react likewise against this devastating chemical pressure foreign to the human body by becoming ill?
• Shouldn’t it be a natural thing to take environmentally sick people seriously?
• Shouldn’t society react by raising the alarm and by initiating serious research in this field?
• Shouldn’t the medical world immediately offer these seriously environmentally sick people fair and thorough medical examination, counseling and treatment for their disabling disease MCS?
• Why is there instead such an extensive and massive objection against accepting MCS as the environmental disease that it is? Who has a special interest to deny chemical sensitivity and instead attempt to explain it away by declaring it to be a mental disease?
• Could it be that the chemical industry, the insurance industry, and certain politicians have a huge interest in not recognizing MCS as an environmental disease due to chemicals?

If MCS was recognized as a disease caused by chemicals, the aforementioned groups would be in very big financial trouble. However, if instead these patients were diagnosed with psychiatric disorders, they would save huge amounts in loss of earnings, claims for damages, disability pension payouts etc., so it is obvious, here we find the reason why globally there is such vigorous objection of fair and thorough research of MCS, and why the limited number of environmental physicians have constant attempts to be discredited by any means possible.

There are always greedy research scientists and physicians who can be bought off to produce predetermined research results, as well as predetermined diagnoses. That was evident with regard to the impact of tobacco on health, and that is also evident with regard to the impact o f chemicals on health. Many physicians diagnose MCS sufferers with psychiatric disorders, but such misdiagnoses do not, of course, make MCS sufferers less chemically sensitive.

On the contrary, increasingly more people do develop MCS – and if the chemical problem is not taken seriously very soon, Stephen Hawking’s prophesy can easily come true. Man is the disaster about to destroy Earth and life on Earth.

MCS suffers are just the first victims. – They are the yellow canaries in the coal mines.

For Immediate Release

Oct. 26, 2010

The sweet smell of fresh laundry may contain a sour note. Widely used fragranced products – including those that claim to be “green” – give off many chemicals that are not listed on the label, including some that are classified as toxic.

A study led by the University of Washington discovered that 25 commonly used scented products emit an average of 17 chemicals each. Of the 133 different chemicals detected, nearly a quarter are classified as toxic or hazardous under at least one federal law. Only one emitted compound was listed on a product label, and only two were publicly disclosed anywhere. The article is published online today in the journal Environmental Impact Assessment Review.

“We analyzed best-selling products, and about half of them made some claim about being green, organic, or natural,” said lead author Anne Steinemann, a UW professor of civil and environmental engineering and of public affairs. “Surprisingly, the green products’ emissions of hazardous chemicals were not significantly different from the other products.”

More than a third of the products emitted at least one chemical classified as a probable carcinogen by the U.S. Environmental Protection Agency, and for which the EPA sets no safe exposure level.

Manufacturers are not required to disclose any ingredients in cleaning supplies, air fresheners or laundry products, all of which are regulated by the Consumer Product Safety Commission. Neither these nor personal care products, which are regulated by the Food and Drug Administration, are required to list ingredients used in fragrances, even though a single “fragrance” in a product can be a mixture of up to several hundred ingredients, Steinemann said.

So Steinemann and colleagues have used chemical sleuthing to discover what is emitted by the scented products commonly used in homes, public spaces and workplaces. The study analyzed air fresheners including sprays, solids and oils; laundry products including detergents, fabric softeners and dryer sheets; personal care products such as soaps, hand sanitizers, lotions, deodorant and shampoos; and cleaning products including disinfectants, all-purpose sprays and dish detergent. All were widely used brands, with more than half being the top-selling product in its category.

Researchers placed a sample of each product in a closed glass container at room temperature and then analyzed the surrounding air for volatile organic compounds, small molecules that evaporate off a product’s surface. They detected chemical concentrations ranging from 100 micrograms per cubic meter (the minimum value reported) to more than 1.6 million micrograms per cubic meter.

The most common emissions included limonene, a compound with a citrus scent; alphapinene and beta-pinene, compounds with a pine scent; ethanol; and acetone, a solvent found in nail polish remover. All products emitted at least one chemical classified as toxic or hazardous.

Eleven products emitted at least one probable carcinogen according to the EPA. These included acetaldehyde, 1,4-dioxane, formaldehyde and methylene chloride. The only chemical listed on any product label was ethanol, and the only additional substance listed on a chemical safety report, known as a material safety data sheet, was 2-butoxyethanol.

“The products emitted more than 420 chemicals, collectively, but virtually none of them were disclosed to consumers, anywhere,” Steinemann said. Because product formulations are confidential, it was not possible to determine whether a chemical came from the product base, the fragrance added to the product, or both.

Tables included with the article list all chemicals emitted by each product and the associated concentrations, although do not disclose the products’ brand names. “We don’t want to give people the impression that if we reported on product ‘A’ and they buy product ‘B,’ that they’re safe,” Steinemann said. “We found potentially hazardous chemicals in all of the fragranced products we tested.”

The study establishes the presence of various chemicals but makes no claims about the possible health effects. Two national surveys published by Steinemann and a colleague in 2009 found that about 20 percent of the population reported adverse health effects from air fresheners, and about 10 percent complained of adverse effects from laundry products vented to the outdoors. Among asthmatics, such complaints were roughly twice as common.

The Household Product Labeling Act, currently being reviewed by the U.S. Senate, would require manufacturers to list ingredients in air fresheners, soaps, laundry supplies and other consumer products. Steinemann says she is interested in fragrance mixtures, which are included in the proposed labeling act, because of the potential for unwanted exposure, or what she calls “secondhand scents.”

As for what consumers who want to avoid such chemicals should do in the meantime, Steinemann suggests using simpler options such as cleaning with vinegar and baking soda, opening windows for ventilation, and using products without any fragrance.

“In the past two years, I’ve received more than 1,000 e-mails, messages, and telephone calls from people saying: ‘Thank you for doing this research, these products are making me sick, and now I can start to understand why,’” Steinemann said.

Steinemann is currently a visiting professor in civil and environmental engineering at Stanford University. Co-authors are Ian MacGregor and Sydney Gordon at Battelle Memorial Institute in Columbus, Ohio; Lisa Gallagher, Amy Davis and Daniel Ribeiro at the UW; and Lance Wallace, retired from the U.S. Environmental Protection Agency. The research was partially funded by Seattle Public Utilities.

For several years the Swedish Prof. Dr. Eva Millqvist researched the disease of hyperreactivity of the respiratory tract and the environmental condition of Chemical Sensitivity (MCS). She specializes in the range of responses to respiratory irritants.

Sick from odors and fragrances

Patients with respiratory symptoms which are triggered by chemicals and odors, are commonly found in allergy clinics. According to Millqvist and her team, these health problems are not explained by asthma or allergic reactions.

German patients frequently report that after they report reactions to chemicals or odors to their allergist, the prospect of seeing a psychologist has been recommended. Whether or not this recommendation is actually appropriate for these patients, it is precisely what this new study from Sweden addresses.

Studies showed reactions

Millqvist’s previous studies have shown that MCS patients often have an increased sensitivity to inhaled capsaicin. This ingredient of chili is famous sensory reactivity. A diagnosis of sensory hyperreactivity of the airways (SHR) is proposed for these kinds of complaints.

In a recent study this renowned scientist and two colleagues, sought to discover whether there is a relationship between asthma and sensory hyperreactivity (SHR). In addition, the research team wanted to investigate whether patients with signs of SHR had increased psychiatric morbidity (anxiety, depression, etc.).

Patients were subjected to tests and questionnaires

The researchers took 724 patients with suspected allergies or asthma from an asthma center. All patients had a questionnaire regarding reactions and behavioral disorders caused by fragrant substances.

A standardized Capsaicin test was carried out and then a questionnaire was given to assess psychiatric morbidity in patients with severe chemical sensitivity to identify those who suffer from SHR.

No evidence of depression or anxiety

Only about 6% of the asthma patients from the allergy center, who participated in the study, had sensory hyperreactivity (SHR). Millqvist and her colleagues stated that this is in consistent with the prevalence in the general Swedish population. There was no significant evidence that SHR is consistent with anxiety or is related to depression.

Patients should insist on precise diagnostic evaluation

The study appeared in the July 2010 issue of the medical journal “Annals of Allergy, Asthma & Immunology.” Those patients who respond to chemicals and odors with hyperreactive respiratory symptoms should perhaps seek an experienced environmental medicine professional if their allergist makes a reference to the possibility of a mental illness.

Indigenous people, diabetes and the burden of pollution

Diabetes is now widely regarded as the 21st century epidemic. With some 284 million people currently diagnosed with the disease, it’s certainly no exaggeration-least of all for Indigenous people.

According to the State of the World’s Indigenous Peoples Report by the United Nations, more than 50 per cent of Indigenous adults over the age of 35 have Type 2 Diabetes, “and these numbers are predicted to rise.”

Diabetes is referred to as a “lifestyle disease,” its rampant spread believed to be caused by obesity due to our increased reliance on the western diet (also known as the “meat-sweet” diet) and our avoidance of regular exercise.

While these may certainly be contributing factors, there is growing evidence that diabetes is closely linked with our environment. More than a dozen studies have been published that show a connection between Persistent Organic Pollutants (POPs) including polychlorinated biphenyls (PCBs); carcinogenic hydrocarbons known as Dioxins; and the “violently deadly” synthetic pesticide, DDT and higher rates of the disease.

“If it is the POPs, not the obesity that causes diabetes, this is really striking if true,” says Dr. David O. Carpenter, director of the Institute for Health and the Environment at the University of Albany.

One out of four Indigenous adults living on reserves in Canada have been diagnosed with Type 2 Diabetes, the most common form of diabetes. The prevalence of the disease appears to be so great that the number of new cases being diagnosed in Canada may exceed the growth of the Indigenous population. It’s no longer uncommon to find children as young as three with the disease. According to government statistics, 27 per cent of all Indigenous people in Canada will have Type 2 Diabetes in the next ten years.

Sandy Lake First Nation, in the Sioux Lookout Zone of northern Ontario, has all but met the mark. A March 2009 study co-authored by Dr. Stewart Harris found that 26 per cent of the community has the disease, the highest recorded rate of diabetes in Canada. With a population of 2,500, the northern Cree community was recently described as an “epicentre” of the epidemic.

There has been little research on the levels of persistent organic pollutants in Sandy Lake; however, according to the First Nations Environmental Health Innovation Network, several neighboring communities who also have high rates of diabetes, like Kitchenuhmaykoosib Inninuwug First Nation, are known to have elevated levels of PCBs in their blood.

The Mohawk community of Akwesasne has its own conflict with diabetes and exposure to POPs. Located across the New York-Ontario-Quebec borders along the St. Lawrence River, three aluminum foundries upriver from the reserve dumped PCBs into the river for decades, contaminating the water, soil, and vegetation.

For many years, Dr. Carpenter has been involved in the study of Adult Mohawks at Akwesasne. Most recently, in 2007, he took part in a study to examine the diabetes/pollution link in the community.

“Our study of adult Mohawks showed a striking elevation in rates of diabetes in relation to blood levels of three persistent organic pollutants, DDE, the metabolite of DDT, hexachlorobenzene and PCBs,” Dr. Carpenter explains. “Our results are quite compatible with those of Lee et al.”

In 2006, Dr. Dae-Hee Lee and her colleagues showed that people with the highest rate of exposure to POPs were roughly 38 times more likely to have diabetes than those with the lowest rate of exposure. Further, “they showed that people who were obese but did not have high levels of POPs were not at increased risk of developing diabetes,” continues Dr. Carpenter. “Probably the reason most people get obese is that they eat too many animal fats, and this is where the POPs are.”

The dietary source of POPs was confirmed by the US Environmental Protection Agency in their Draft 1994 Dioxin Reassessment, which has never been formally released to the public. According to the Draft Reassessment, 93 per cent of our exposure to Dioxin comes from the consumption of beef, dairy, milk, chicken, pork, fish, and eggs; in other words, the western diet.

A May 2001 study published in the Journal of Toxicology and Environmental Health drew similar conclusions to the EPA Reassessment. In addition, the study found that “nursing infants have a far higher intake of dioxins relative to body weight than do all older age groups,” and that human breast milk was twice as toxic dairy milk. It also found that vegans had the overall lowest rate of POPs in their bodies.

According to an October 2009 paper by the Research Centre for Environmental Chemistry and Ecotoxicology at Masaryk University, another major source of POPs, specifically DDT, is the world’s oceans. The paper also found that despite restrictions placed on the use of DDT more than 30 years ago, concentrations of the toxin are on the rise.

Indigenous people carry an unequally high proportion of this global toxic burden. For instance, according to Environment Canada’s National Pollutant Release Inventory (NPRI) there are 212 Indigenous communities in Canada living near or downstream from pulp mills and other facilities that produce dioxins and furans. One striking example is the old Dryden pulp mill near Grassy Narrows which, according to the Grassy Narrows and Islington Bands Mercury Disability Board, dumped tonnes of dioxin-laced mercury wastewater into the English-Wabigoon River system from 1962-70.

Forty years later, the poisonous waste continues to pose a “serious health threat” to Grassy Narrows and the Wabaseemoong First Nations, says the Disability Board. No formal steps have been taken toward remediation by federal or provincial governments.

The Tohono O’odham Nation’s experience bears a close resemblance to Grassy Narrows: the world’s highest rate of diabetes can be found in the southwest Arizona nation. According to Tribal health officials, nearly 70 per cent of the population of 28,000 has been diagnosed with the illness. The O’odham People make up the second largest Indigenous Nation in the United States.

Lori Riddle is a member of Aquimel O’odham Community and founder of the Gila River Alliance for a Clean Environment (GRACE).

GRACE was instrumental in the 10 year struggle against a hazardous waste recycling plant that operated without full permits on O’odham land for decades. Owned by Romic Environmental Technologies Corporation, the plant continuously spewed effluents into the air until it was finally shut down in 2007.

The Romic plant was not the first contributor to the O’odham’s toxic burden, explained Riddle. Looking back to her childhood, she recalled: “For nearly a year, [when] a plane would go over our heads, you could see the mist. We never thought to cover our water. The chemicals just took over and they became a part of us.”

From the early 1950s until the late 60s, cotton farmers in the Gila River watershed routinely sprayed DDT onto their crops to protect them from bollworms. According to the Agency of Toxic Substances and Disease Registry (ATSDR), each and every year, the farmers used roughly Twenty-three pounds of DDT per acre.

In 1969, the State of Arizona banned the use of DDT; by this time the river was gravely contaminated. According to the ATSDR, farmers then switched to Toxaphene, a substitute for DDT-until it was banned by the US government in 1990.

Because of these chemicals, Riddle explains, the O’odham were forced to abandon their traditional foods and adopt a western diet. Farms also went into a recession, forcing many families to leave their communities. Companies, such as Romic, began moving on to their territory, exasperating the situation. “It’s taken a toll on our quality of life,” she says. “I’ve cried myself to sleep.”

The O’odham are dealing with what Riddle terms “cluster symptoms” including miscarriages, arthritis in the spine, breathing problems, unexplainable skin rashes, and problems regenerating blood cells. This in addition to diabetes, which frequently leads to renal failure, blindness, heart disease, and amputations.

More and more studies are being published that show the link between diabetes and persistent organic pollutants like DDT-stemming from the landmark “Ranch Hand” study. In 1998, the study found a 166 per cent increase in diabetes (requiring insulin control) in US Air Force personnel who were sprayed with the herbicide and defoliant Agent Orange during the Vietnam War. The study also found that as dioxin levels increased so did the presence and severity of Type 2 diabetes, the time to onset declined following a similar trend.

However, Dr. Carpenter notes that because of the widely-endorsed belief that diabetes is a life-style disease related to diet and exercise, the link is gaining little attention by governments, news agencies, or by any of the hundreds of non-profit diabetes foundations around the world. “[It] hasn’t even made it into the medical community at this point,” Dr. Carpenter adds. “It takes a long time to change both medical and public opinion.”

“Clearly one thing everyone can do is to eat less animal fats,” suggests Dr. Carpenter. Several Indigenous communities in northern Manitoba and British Columbia have begun to do this, planting their own gardens and building greenhouses; returning, in a traditional sense, to some of the foods that sustained them for millennia. Others are turning to exercise, which plays a vital role not just in the prevention of diabetes, but in their overall health.

“Also, we must find ways of getting the POPs out of the animals that we eat. That is not going to be easy, given how contaminated we have made the world,” adds Dr. Carpenter. For this, Lori Riddle, who is herself a diabetic, points to the Tribal Council and the Federal Government.

Yesterday (Feb 2, 2010), in an independent student newspaper from the University of New Hampshire, a professor of chemical engineering appealed to the community to take “Canaries” into account regarding the use of chemicals and especially scents. He spoke of those persons who suffer from Chemical Sensitivity and who have to be seen – like those former canaries in mines – as indicators for toxic chemicals.

Some American and Canadian Universities have a “Scent Free Policy” which means that the use of perfumes and products containing scents is prohibited within these Universities. All visitors have to meet this policy. It allows students with allergy and chemical sensitivity to work and study.

Professor Ihab Farag, Chemical Engineering Department:

Many of us are familiar with canaries, the beautiful, colorful birds that tend to sing most of the time. Canaries also saved many human lives in coalmines. This is because canaries are much more sensitive to toxic gases than humans. Miners would take canaries with them in the coalmine. If the canary stopped singing and fell (or died), the miners knew to leave the coal mine quickly to safety.

There are individuals who have developed a very strong sensitivity to many common chemicals. These people can be very negatively affected and irritated by fumes, chemical cleaners, disinfectants, cigarette/cigar smoke, engine exhaust, solvents, etc. These people are often called “Human Canaries” of the modern world, because of the chemical sensitivity similarity to that of Canaries. Human Canaries of the 21st century tend to be very strongly irritated by everyday chemicals like perfumes, hair products, shampoos, shower gels, after shave lotions, antiperspirants, deodorants, hand sanitizers, chap sticks, finger nail polish, etc. Human canaries look the same as other people, and when you see one you probably will not recognize he or she is a human canary until an offensive toxic chemical triggers his or her sensitivity.

Please be considerate to human canaries and help them to enjoy life to the fullest. One way you can help the human canary and at the same time lower your exposure to undesirable chemicals, is to go fragrance-free: avoiding perfumes, and fragranced personal care products.
